What is Achilles tendinopathy?
Achilles tendinopathy is a condition causing pain, stiffness, and swelling of the Achilles tendon — the thick band of tissue connecting your calf muscles to your heel bone. It is a common, manageable condition, and understanding what's actually happening in the tendon is the first step toward a confident recovery.
Unlike a sudden sports injury, Achilles tendinopathy is usually cumulative. It develops after a change in activity load — doing noticeably more, or sometimes noticeably less, than the tendon is currently conditioned to handle. A runner increasing weekly mileage, someone returning to hiking after months away, or a person who has recently become more sedentary can all develop it. Diagnosis is typically made clinically, based on your symptoms and a physical examination; imaging such as ultrasound or MRI is usually not required to start treatment.
It's worth being clear about what this condition is not: it is distinct from a full Achilles tendon rupture, which is a sudden, complete tear of the tendon and requires urgent medical assessment rather than a physiotherapy programme (see the safety note below).
Achilles tendinopathy is genuinely common. Among people who exercise, the overall prevalence is estimated at around 6%, rising to about 8% in those over 45 and as high as 17% in gymnastics (Prevalence of Achilles tendinopathy in physical exercise, PMC 2022). Among athletes more broadly, the cumulative lifetime incidence is estimated at around 24%, with a reported frequency of about 9% among recreational athletes specifically (Achilles Tendinopathy, StatPearls/NCBI). There are also two recognisable patterns: midportion tendinopathy (pain in the tendon body, a few centimetres above the heel) accounts for roughly 64% of cases, while insertional tendinopathy (pain right where the tendon attaches to the heel bone) accounts for about 28% — a distinction that matters because the two respond somewhat differently to loading exercises (Epidemiology of insertional and midportion Achilles tendinopathy in runners, PMC).
How home physiotherapy helps
The core, evidence-supported treatment for Achilles tendinopathy is structured exercise — specifically, progressive loading of the calf muscles and tendon. This isn't about rest and waiting for pain to pass; tendons respond to being loaded in the right way, at the right dose, and physiotherapy exists to find and progress that dose safely.
Clinical guidance is consistent on this point: structured physiotherapy aimed at increasing muscle strength and load tolerance, while progressively reducing pain, is the core management approach, and recovery typically takes several months or more of consistent exercise loading (Achilles Tendinopathy, NHS inform Scotland). Delivering this in your home means your physiotherapist can assess your actual walking surfaces, stairs, footwear, and daily movement patterns — the real-world context the tendon has to cope with — rather than working from a generic clinic template.
A home-based programme also supports the consistency that tendon rehabilitation depends on. Because exercises like heel drops are typically done once or twice daily, having a physiotherapist establish correct technique, load, and progression in your own space makes it easier to stay on track between visits.
What a home physiotherapy visit looks like
A first visit typically starts with understanding your symptom history — when the pain started, what activity changes preceded it, and how it behaves with different movements — followed by a physical examination of the tendon, ankle range of motion, and calf strength. Because Achilles tendinopathy is a clinical diagnosis, this assessment is usually sufficient to begin treatment without imaging.
From there, your physiotherapist will introduce an initial loading exercise appropriate to your irritability level (isometric holds if the tendon is particularly reactive, or heel raises if it can tolerate more), review your footwear and any obvious biomechanical contributors, and set a home exercise plan with clear instructions on dosage — sets, reps, and how much discomfort is acceptable during exercise versus a sign to ease off.
Follow-up visits are used to progress the loading programme in a structured way — increasing resistance, tempo, or range as your tendon adapts — and, in longer-standing or sport-related cases, to eventually introduce running or jumping drills as part of a graduated return to activity.
Typical recovery timeline
Tendon tissue remodels slowly, so recovery from Achilles tendinopathy is a gradual, staged process rather than a quick fix — and setting that expectation early tends to make the process feel more manageable, not less encouraging.
Mild, early-stage cases may settle within 2–6 weeks with activity modification and guided loading. However, most structured physiotherapy programmes — whether eccentric loading or heavy slow resistance training — run for a minimum of 12 weeks, and this is where the strongest evidence sits. A well-known long-term study of the eccentric heel-drop protocol tracked patients' VISA-A score (a standard measure of Achilles symptoms and function) rising from 49.2 at baseline to 83.6 at 5 years, indicating substantial and durable improvement over time (5-year follow-up study of Alfredson's heel-drop exercise programme, PMC). Meaningful strength and pain gains are typically seen around the 12-week mark, with continued improvement out to 6–12 months, particularly in longer-standing cases or those with higher physical demands, such as running or sport.
As a general pattern, the longer symptoms have been present before starting treatment, the longer recovery tends to take. A graduated return to running or sport is only introduced once specific pain and strength criteria have been met, which helps protect the progress already made.
Exercises and approaches used at home
Your physiotherapist will select and progress from an evidence-based toolkit, tailored to how irritable your tendon is and what you want to return to:
- Eccentric heel-drop exercises (the Alfredson protocol) — calf raises performed on a step with both straight and bent knee, typically done twice daily. This remains the original and most extensively studied exercise treatment for midportion Achilles tendinopathy (Eccentric exercise is more effective than other exercises in mid-portion Achilles tendinopathy, PMC).
- Heavy slow resistance (HSR) training — progressive calf-raise loading at around 70% of your one-rep max, performed slowly, typically three times a week. A randomised controlled trial of 58 patients found HSR produced equally good, lasting improvement compared with the standard eccentric protocol at both 12 and 52 weeks, with higher patient satisfaction at 12 weeks (Heavy Slow Resistance Versus Eccentric Training as Treatment for Achilles Tendinopathy, PubMed).
- Isometric calf holds — often used early on to help settle pain before progressing to heavier loading.
- Calf and ankle mobility work — to address stiffness that commonly accompanies the condition.
- Progressive functional and plyometric loading — hopping and running drills introduced later, as return-to-sport preparation once criteria are met.
- Activity and load modification, plus footwear or biomechanical review — run alongside the exercise programme to reduce unhelpful strain while the tendon rebuilds capacity.
Across the available evidence, eccentric-style exercise consistently emerges as more effective than other exercise types for improving pain and function in midportion Achilles tendinopathy, which is why it anchors most home programmes (PMC systematic review and meta-analysis).
A safety note
Most Achilles tendon pain is tendinopathy and responds well to physiotherapy — but a small number of presentations need urgent medical attention instead of a home visit. Seek urgent medical assessment if you experience a sudden "pop" or "snap" at the back of the ankle, are unable to bear weight or push up onto your toes, notice a palpable gap in the tendon, or have significant sudden swelling and bruising — these can indicate an Achilles tendon rupture. Separately, after any Achilles injury, new calf pain, one-sided leg swelling, breathlessness, or chest pain warrant immediate medical attention, as these can be signs of a blood clot (DVT/PE).
Taking the next step
Achilles tendinopathy responds well to a clear, consistent, progressively loaded exercise programme — and while it takes patience, the pattern in the evidence is genuinely encouraging: structured loading, given time, reliably improves both pain and function. The most important variables are starting the right exercises at the right dose, and staying consistent long enough for the tendon to adapt.
If you're dealing with Achilles pain that's affecting your walking, running, or daily activity, a home physiotherapy visit is a straightforward way to get an accurate assessment and a personalised loading plan, built around your home, your schedule, and your goals.
